<p>PROBLEM TO BE SOLVED: To improve the resolution of bearing measurements and to separate and identify plural targeted objects even though they are located close to each other in a region. SOLUTION: There exist n transmission pulses within a horizontal beam width of a radar by the rotation of the radar antenna and the radiation of transmission pulses. Then, at least n memories are provided. Let a first pulse be the transmission pulse from which a first receiving signal is obtained from a certain targeted object, M1 be its receiving data andΦ1 be the bearing at that time. Then, M1 andΦ1 are stored in a first memory. Then, the initial bearing of the object is computed fromΦ1 . Then, the difference data are obtained by subtracting the data stored in the memory by a previous pulse contained in the beam width from the received data from the targeted object for every transmission pulse after a second pulse and the difference data are made as the data by the pulse and the data are successively stored in the memory with the bearing angle at that time. Then, a discrimination is made to determine whether the difference data are zero or not and if the data are zero, the terminal bearing of the targeted object is computed based on the bearing angle at that time.</p> |
